libuv is a multi-platform C library that provides core functionality for asynchronous I/O operations, event loops, timers, and other system-related functionalities. It serves as the underlying foundation for the non-blocking I/O operations in Node.js...
Node.js achieves this through the use of an event loop. The event loop listens for events, such as the completion of an I/O operation, and then places the corresponding callback function on an event queue. The Node.js runtime processes the event queu...
process.nextTick() and setImmediate() are two ways to schedule a callback function to be executed in the next iteration of the event loop. However, there are some differences between them: process.nextTick() runs the callback before any other I/O ev...
In Node.js, the event loop is a continuous loop that waits for external events and executes the associated event handlers. It is responsible for handling asynchronous I/O operations and making it possible for Node.js to perform non-blocking I/O opera...
Callback hell is a term used to describe a situation in JavaScript where the code becomes deeply nested with many levels of callbacks, making it difficult to read and understand. This can happen when writing asynchronous code that relies heavily on c...
module.exports is the object that's returned as the result of a require call. You can use it to export a single value or a list of values. It helps in achieving modular programming. // Define a value. const myValue = 'Hello, World!'; // Export the v...
